BACKGROUND AND OBJECTIVES: Being probably of embryonal in origin, the nasolabial cyst is relatively rare and is thought to arise either from the epithelial remnants entrapped along the lines of fusion during the development of face or from the remnants of the developing nasolacrimal duct. The purpose of this study was to examine the clinical and radiological features of nasolabial cyst in order to provide basis for its correct diagnosis and treatment. MATERIAL AND METHODS: The nine cases of nasolabial cyst which were treated in Masan Samsung Hospital from January in 1991 to April in 1997 were the used as subjects. These cases were examined according to age and sex distribution and their clinical features, radiologic and histologic findings, treatment and prognosis, were studied. RESULTS: In our study of nine cases of nasolabial cyst, more females than males were observed, and with respect to age, individuals in their Fortise were more frequently noted. Also, swelling of nasolabial fold were the most frequently observed among symptom and signs. Computerized tomography shows well-circumscribed cystic mass lateral to pyriform aperture. Seven cases underwent operation. Six cases were excised by intraoral sublabial approach, one case which forms fistula to skin was removed by transcutaneous approach. CONCLUSION: Nasolabial cyst is benign harmatomatous cyst of face. This lesion is often unrecognized or confused with other intranasal mass, other fissural and odontogenic cysts, midface infection, or swelling in the nasolabial area. Therefore careful clinical and radiologic evaluation should be considered in the differential diagnosis.

After the performance of 100 coronary cineangiographies in 100 paitents who were adminitted to Soonchunhyang University Hospital under the diagnosis of ischemic heart disease from July 1986 to October 1987, we observed the coronary collateral circulation and measured the ejection fraction, circumferential fiber shortening, left ventricular end-diastolic pressure and pulmonary artery wedge pressure in 52 paitents who had 50% or more stenosis in one or more coroanry arteries. The results were as follow : 1) The collaterall circulation was observed in 16 patients(30.8%) of the 52 patients and it was developed mainly(87.5) in patients with 90% or more coronary artery stenosis. In patients with stenosis of less than 90%, however, collateral circulation was observed rarely(12.5%). 2) The left ventricular wall motion abnormality was severe in the group without collateral circulation. 3) The collteral circulation was most frequently developed in patients with severe right coronary artery stenosis and most of the routes were supplied from contralateral coronary arteries. 4) There was no significant difference in ejection fraction, circumferential fiber shortening, left ventricular end-diastoic pressure and pulmonary artery wedge pressure between the 2 groups with and without coronary artery collateral circulation.

Thirty-one male sexual dysfunctional patients were selected to investigate their depression, anxiety, stress perception, and coping strategy. They were examined by Beck's Depression Inventory, State-Trait Anxiety Inventory, Symptom Checklist-90-Revised, Global Assessment of Recent Stress Scale and Coping Strategy. Twenty-seven healthy normal adults were selected as control group. The results were as follows: 1) Depression and anxiety scores were significantly higher in the patients. 2) Stress perception of usual life, especially work, job and change in relationships, was significantly higher in the patients. Frequency of negative life events was significantly higher in the patients. 3) As coping strategy, intellectualisation, redefinition and compliance were most frequently used by the patients. Most of the patients showed tendency to deny their vulnerabilities. Patients who lived with spouse showed more active confrontation and less emotional turmoil, anxiety and fear than patients who lived without spouse.

BACKGROUND: The purpose of this study is to assess the validity and reliability of general job satisfaction (JS) in the Korean Labor and Income Panel Study (KLIPS). METHODS: We used the data from the 17th wave (2014) of the nationwide KLIPS, which selected a representative panel sample of Korean households and individuals aged 15 or older residing in urban areas. We included in this study 7679 employed subjects (4529 males and 3150 females). The general JS instrument consisted of five items rated on a scale from 1 (strongly disagree) to 5 (strongly agree). The general JS reliability was assessed using the corrected item-total correlation and Cronbach's alpha coefficient. The validity of general JS was assessed using confirmatory factor analysis (CFA) and Pearson's correlation. RESULTS: The corrected item-total correlations ranged from 0.736 to 0.837. Therefore, no items were removed. Cronbach's alpha for general JS was 0.925, indicating excellent internal consistency. The CFA of the general JS model showed a good fit. Pearson's correlation coefficients for convergent validity showed moderate or strong correlations. CONCLUSION: The results obtained in our study confirm the validity and reliability of general JS.

PURPOSE: The activator of protein kinase A, cyclic AMP, has been a recognized growth inhibitor of certain cell types. The present study aimed to investigate the effects of dibutyryl cAMP on the growth of cancer cells which lack wild-type p53 and to determine the mechanism of growth inhibition. MATERIALS AND METHODS: Prostate and breast cancer cells were treated with dibutyryl cAMP and compared with untreated cells. Growth patterns of cells were assessed by trypan blue-excluding method and western blot was done to determine protein levels of cell cycle regulatory proteins which govern G1 and G1/S phase. Northern blot and immunoprecipitation were done to determine the level of mRNA of p21 and the association between cell cycle regulatory proteins. In vitro immune complex kinase assay was done to assess the activity of cdk2. RESULTS: cAMP reduced cell growth by 48 h. Cyclin D3 level was downregulated and RB protein level was decreased and mostly unphosphorylated forms remained. The association of RB with E2F1 was increased. While cdk2 levels remained constant throughout cAMP treatment, the activity of cdk2/cyclin E complex, which is responsible for entry into S phase, was downregulated. Cdk inhibitors, p27 and p21 were induced with cAMP treatment. CONCLUSION: These observation suggest that the growth inhibitory effects of dibutyryl cAMP on prostate and breast cancer cells were mediated by induction of cdk inhibitors such as p21 and p27 and RB activation in accordance with downregulation of cdk2.

BACKGROUND: Arterial hypoxemia has been noted in patients with liver cirrhosis because of bronchial vessel dilatation. Cabenes et al. reported that bronchial hyperresponsiveness to the metacholine inhalation was observed in patients of left side heart failure, he suggested that one of the mechanism was bronchial vessel dilatation. We hypothesized that patients of liver cirrhosis might have bronchial hyperresponsiveness to metacholine inhalation due to portal hypertension. We evaluate the relationship between bronchial responsiveness and severity of liver cirrhosirs, severity of portal hypertension. METHODS: In the 22 patients of the liver cirrhosis with clinical portal hypertension metacholine provocation test was done and determined PC20 FEV1. We classified lifter cirrhosis according to Pugh- Child classification Esophagogastroscopies were performed for the evaluation of the relationship between bronchial hyperresponsiveness and severity of esophageal varix. RESULTS: In the 22 cases of the liver cirrhosis with clinical portal hypertension. The causes of liver cirrhosis, alcoholic hepatitis was 9 cases. hepatitis B virus was 12 cases, hepatitis C virus was 1 case. and 151 cases (68.18%) of total 22 cases were positive in metacholine provocation test. In positive cases There was no significant relationship between PC20FEV1 and severity of liver cirrhosis which were classified by Pugh-Child classification or severity of esophageal varix(p<0.05). CONCLUSION: we observed that bronchial responsiveness to metacholine increased in the patients of liver cirrhosis and there was no significant relationship between the severity of liver cirrhosis and the severity of esophageal varix.

The management of the third molar tooth in mandibular angle fracture is still controversial. Retrospective analysis of 197 cases of mandibular angle fractures associated with third molar tooth was undertaken. Selective prophylactic extraction of the third molar teeth were undertaken in 66 cases. The third molar teeth were retained in 131 fractures. The indication of extraction of the third molar teeth in mandibular angle fracture were as follows: 1) interfering with reduction of the fracture; 2) excessive mobility; 3) exposure of tooth root due to distraction of the fracture; 4) fractured teeth; 5) severely carious tooth 6) infected supporting structure. There were no significant differences between the complication rate in the "tooth removed" group and "tooth retained" group. Complications were minimal. Therefore proper management of the third molar tooth in mandibular angle fracture will minimize complication.

PURPOSE: Complete release of the transverse carpal ligament(TCL) is accepted as the standard treatment for carpal tunnel syndrome(CTS). However, loss of grip and pinch power are reported in some patients after complete release of the TCL. This study was designed to evaluate the effectiveness of complete versus partial carpal tunnel release by using the inching technique. METHODS: Nineteen patients(a total of 27 hands) who each had a confirmed diagnosis of CTS were selected from September 2002 to February 2003. The cases were divided into three groups(mild, moderate and severe) based on preoperative electrodiagnostic studies. The patients with partial carpal tunnel syndrome were classified into the mild or moderate groups, while patients with complete carpal tunnel syndrome were classified into the moderate or severe groups. Patient oriented data (functional and symptomatic) were collected and electrophysiologic studies were undertaken preoperatively and postoperatively(on the 2nd week, 1st month, 3rd month and 6th month after surgery). RESULTS: In this study, the mild and moderate groups showed both good functional and symptomatic results and improvements in electrophysiologic studies. CONCLUSION: Carpal tunnel syndrome patients classified into mild or moderate groups based on nerve conduction studies, and whose precise compression sites were pinpointed using the inching technique, can be treated by partial carpal tunnel release.

BACKGROUND AND OBJECTIVES: The human vestibule is known to be able to induce cervical muscle potential secondary to strong acoustic stimulations. This reflex is assumed to originate in the saccule, and is called "vestibular evoked myogenic potentials" (VEMP). The responses consist of alternatively positive and negative successive waves (p13-n23). This study was designed to evaluate the clinical significance of VEMP. MATERIALS AND METHOD: We studied the difference among the latencies of p13, n23 and the amplitudes among the 10 normal volunteers, 5 patients with sudden sensorineural hearing loss and 10 patients with vestibulopathy. And we compared the result of the caloric test and VEMP in patients with vestibulopathy. RESULTS: In the normal group, VEMP was detected in all and all of the sudden sensorineural hearing loss patients showed VEMP both in the affected and unaffected side. In unilateral vestibulopathy patients, VEMP were present in the unaffected side but not in the affected side. The difference between the amplitudes and latencies were not found in those cases where VEMP was detected. In vestibulopathy patients, VEMP were well correlated with the result of the caloric tests. CONCLUSION: We confirmed that VEMP is originated from the vestibule, not from cochlea. VEMP could provide itself as an addition method for testing the vestibule.
